appearance
🪞 外貌 = 外 (outside) + 貌 (looks) = the outward look someone shows
外 means outer or external; 貌 means countenance or looks. Stack them and you get the external looks, i.e. someone's appearance or profile.
外 — evening 夕 + divination 卜
Originally a compound of 夕 (evening) and 卜 (divination). Ancient Chinese divinations were performed in the morning; doing them at evening (夕) was considered irregular or 'outside' the norm. From this sense of deviation, 外 came to mean 'outside' or 'external'.
